I'm using Fedora GNU/Linux 13 on a 64-bit AMD system with 4GB RAM (around 3.6GiB of RAM is visible according to the system monitor program one runs via System -> About This Computer).  I'm running Linux kernel 2.6.33.4-95.fc13.x86_64 (a Fedora kernel package).

I can't imagine that there is a shortage of RAM for a 1TB filesystem.  We run e2fsck on 3x 8TB filesystems with only 2GB of RAM.

What is more important to know is why it thinks the block/inode bitmaps and
inode table need to be relocated in the first place.  That is a pretty serious/significant problem that should normally never been seen, since the bitmaps never move, and there are backups of all the group descriptors (that say where the bitmaps are located).

Did you do something like resize your filesystem before having this problem?
